MY NOTES ASK YOUR TEACHER You are supposed to meet a friend in another city that is 250 km away on the interstate. You are supposed to meet them at 11:15 A. M. You plan to drive at 100 km/h, so you leave at 8:00 A. M. to allow some extra time. You drive at that speed for the first 100 km, but then construction work forces you to slow to 55 km/h for 40 km. What would be the least speed needed for the rest of the trip to arrive in time to meet your friend

Two horizontal plates with infinite length and width are separated by a distance h in the z direction. the bottom plate is moving at a velocity u. the incompressible fluid trapped between the plates is moving in the positive x-direction with the bottom plate. align gravity with positive z. assume that the flow is fully-developed and laminar. if the systems operates at steady state and the pressure gradient in x-direction can be ignored, do the following: 1. sketch your system 2. identify the coordinate system to be used. 3. show your coordinates and origin point on the sketch. list all your assumptions. 5. apply the continuity equation to your system. nts of navier stokes equations of choice to your system 7. solve the resulting differential equation to obtain the velocity profile within the system make sure to list your boundary conditions. check units of velocity 8. describe the velocity profile you obtain using engineering terminology. sketch that on the same sketch you provided in (1). 9. obtain the equation that describes the volumetric flow rate in the system. check the units.

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

The energy of a photon was found to be 3.38 × 10–19 j. planck’s constant is 6.63 × 10–34 j • s. which color of light corresponds to this photon?
